Crystal packing of compound (I) (a) along the a axis, and (b) along the c axis. In (a), neighboring layers are shifted relative to one another while in (b) they are held together by O—H⋯O hydrogen bonds between hydroxide oxygen atoms and carboxylate group oxygen atoms [O1⋯O10iv = 2.811 (4) Å, O1—H1O⋯O10iv = 156°; symmetry code: (iv) −x + 1, y − , −z + ]. |
